Should you close the flue to the fireplace to keep the humidity out of the house?
The purpose of the fireplace damper is to keep the outside elements, outside. The damper is opened only when there is a fire in the fireplace.
How does a fire damper work?
In the event of fire, the fusible link melts and the shutter gets closed. This helps in blocking the fire from spreading through the duct ----- If you are asking about a damper on a stove or chimney, that is not called a fire damper, but just a damper. There is a link to a question on that below.
What does a Steering damper on a VW bus do?
A steering damper serves the same purpose as a shock absorber. Dennis
How does a damper work?
A damper restricts the air flow. In a fireplace, the damper is closed to prevent air from going up the chimney, with a resulting loss of heat in the house, when the fire is not going. When a fire is to be started, the damper is opened to create a draft to vent the smoke. In a wood or coal burning stove, the damper is variable and can be used to regulate the draft. The more widely open the damper is, the greater the draft, and the hotter to fire burns. This sort of damper cannot be closed all the way, because it is necessary to vent slow fires. Sometimes, a stove will have multiple dampers for different purposes. For example, a wood cook stove will have typically a damper on the flue, to regulate the heat of the fire, and a separate damper so the cook can choose to vent the gasses from the fire directly into to chimney, which would be how a fire is started, or around the oven, so the oven can heat nicely once a good draft is established. In other systems where air is moved, dampers can be used to stop the motion of the air. A fire damper is one such system, where the damper is used as a safety device to prevent a fire from spreading. There are links below.
What is the difference between damper and bread?
The difference between bread and damper is simply just that damper is traditionally cooked on the ashes of the fire and sometimes has baking soda .
What is the meaning of a chimney cap damper?
A top damper or cap damper is a metal spring door placed at the top of the chimney with a long metal chain that allows one to open and close the damper from the fire place.
Information about fire damper?
A fire damper isolates and area by using a fusable link that will melt at a specific temperature that then aallows a dampoer to close to either isolate a room, area or HVAC duct. The damper is located when duct passes through a fire rated wall or for a return air opening.
What is the purpose of a tuned mass damper?
to solve vibration problems
What is the difference between smoke damper and firesmoke damper?
Assuming your question relates to life safety in building construction, and not to parts of a wood burning device- Smoke dampers are intended to limit the movement of smoke within a building, or section of a building. They are not intended to inhibit FLAME spread. A fire damper will inhibit smoke movement, but is also insulated to stop fire. A simple smoke damper might be light weight sheet metal- but that is not enough to stop very high temprature. A fire damper is heavier, may be insulated, built of fire resistive material, etc.
What is the fire dampers?
Frequently Asked Questions About Fire and Smoke DampersWhat is the purpose of a fire damper?Fire Dampers are used to maintain the required ratings of fire rated barriers (walls, partitions, floors) when they are penetrated by ductwork.How does a fire damper work?When a rise in temperature occurs a fire damper will close and prevent the spread of flame through the barrier. Dampers are typically curtain style that will close (shut) when a fusible link melts. The fusible link typically melts when the temperature rises to 165 degrees Fahrenheit. In some circumstances higher degree fusible links (e.g. 212°F) are installed in ductwork with consistently higher normal temperatures, such as hot decks in dual duct systems. Fire dampers are certified by Underwriters Laboratories (UL) to carry hourly fire resistance ratings, typically 1.5 to 3 hours.What is the purpose of a smoke damper?Smoke dampers are used is ductwork and air transfer openings that are designed to resist the passage of air and smoke. Smoke dampers may be required in smoke barriers and other smoke controlled systems.How does a smoke damper work?Typically smoke dampers are operated by smoke detectors in the ductwork that will close the smoke damper when smoke is detected. Smoke detectors often are hard wired to a central alarm panel in which the alarm will relay a signal to the smoke damper to cause smoke damper closure. The closure of smoke dampers are done by an actuator - the actuator is either electric or pneumatic. The actuator utilizes the jackshaft and linkage to open and close the blades of the smoke damper. Smoke dampers are UL certified with an air leakage class rating.What is a Combination Fire and Smoke Damper?These dampers are used in areas where both smoke and fire barriers are located to prevent the passage of both smoke and flames.What is a Corridor Damper?Corridors are means of egress travel to an exit. Corridor dampers are fire and smoke dampers that have been designed for use in corridors.What is a Ceiling Damper?Ceiling dampers lessen the passage of heat in fire resistance ceilings where ducts are made only through ceilings.What is a fire barrier?Fire barriers are fire-resistant rated horizontal or vertical assemblies designed to stop the spread of fire.What is a smoke barrier?Either vertical or horizontal, the smoke barrier is a continuous surface such as a wall, floor, or ceiling constructed to restrict the movement of smoke.
Should the damper stay all the way open when you have a fire going?
yes
Can you adjust the damper while you have a fire?
yes you can,as long as is it doesnt cause the smoke to roll out,your fire will last all night
